Title states. Bought these, opened to check them out a couple weeks ago, and changed my mind. They are the ones here if you have question about fitment years:

Also took them and the clamps out of the box for a picture. Kind of self explanatory, these are the 304SS ones according to the website and have the clamps that are not guillotine clamps. Never used, been sitting in my house. Paid 160 shipped. Looking for 120+ shipping. If you want to pick them up, 100 bucks in North Jersey. Zero feedback on this forum but have done a bunch of transactions on G8 Board and LS1tech (back in the day) if you want to look.
